Walworth Forged Steel Y Piston Check Valve

Walworth Forged Steel Y Piston Check Valve


"Y" Pattern Piston Check Valves are generally used to protect pumps or similar equipment, allowing the flow in only one direction and preventing flow reversal due to back pressure. Also is used when a laminar flow and increased CV is desired.

This design provides a tight seal as well as a fast reaction to the closure impulse.

Metal seated check valves may not provide drop tight sealing when used in gas system or fluid system with low back flow pressure or fluids contaning particles.

  • Valves in accordance with API-602.
  • Socket weld, threaded, combined or flanged RF or RTJ ends.
  • Bolted or Welded Bonnet options.
  • Low fugitive emissions control.
  • Nace service either MR-0175 or MR-0103
  • Test in accordance with API-598.
  • Horizontal Fluid Control
  • Vertical Fluid Control with Spring
  • Body to cover joint designed to apply a uniform load to the gasket to assure a leak proof seal.
  • Guided piston to assure a correct seal.
  • Spring to allow a mounting in a vertical line available upon request.
  • Stellite seat provides increased resistance to wear abrasion and erosion of sealing surface.

Walworth's valves are designed and manufactured to meet the most stringent special requirements of various industries, including power generation, chemical and petrochemical, oil and gas, pulp and paper, mining, cryogenic and ship building applications.
